View Full Version : What tools will I need and how difficult is it to replace a Wheel bearing-93 LeSabre kdaddy 12-24-2005, 09:44 PM I recently read a Chiltons manual for this procedure and they suggested removing the actual axle. I thought this was excessive. Please give me some suggestions as to what tools and procedures. This would be of great help. Thanks Kdaddy heidigirl 12-25-2005, 12:12 AM i had to replace this part on an 88 cutlass and the parts may have changed slightly, but the procedure is not too difficult. all that is required is basic metric wrenches and sockets. remove the caliper and rotor to gain access to the four bolts holding the bearing carrier to the suspension assembly. a large wheel puller makes the job easy, but with patience, you can simply wedge it out with a blade screwdriver. there is an o'ring buried in there someplace, so be careful not to cut it. the bearing itself, is a press fit into the carrier, so don't get any allusions about replacing just the bearing. a fresh replacement is around $90.00 at NAPA, but if you are not afraid of parts having some experience, a junk yard piece will run about $25.00. guyopel 12-25-2005, 02:24 PM Your '93 Buick hub bearing is easy to remove if you have an air impact gun and basic hand tools ., but the socket to remove the axle nut is metric 36mm .If you donot have these tools it might be best to pay a shop to replace your axle hub .. the axle nut must be very tight or you can do a lot of damage to the front end . HTH Guyopel heidigirl 12-26-2005, 03:32 PM sorry that i forgot about the 36mm nut. guyopel is right, you will need an impact wrench to remove it. i don't see you breaking it loose with hand tools unless a lot of leverage is applied. kdaddy 12-26-2005, 07:43 PM You didn't mention anything about the lower ball joint. I thought it would be necessary to remove the cotter pin and nut and pry it apart. Yes or No? Thanks again for everything. Kdaddy jazzbass 12-27-2005, 07:57 AM You don't need to mess with the ball joint. The bearing assembly is bolted into the steering knuckle. If you don't have an impact wrench you should be able to loosen the 36mm nut with a breaker bar. With the car on the ground set the emergency brake while in park. Mark the nut and shaft with a dab of paint to use as a reference when you tighten the CV shaft back up. Good Luck |
